, LAMP SHADE Application filed December 18, 1930. Serial No. 503,311.

This invention relates to a lamp shade which is designed and adapted to be used in dentists and doctors operating rooms and other work rooms.

The invention contemplates a lamp which is adapted to permit light rays from a lamp to pass upwardly and downwardly to illuminate the upper and lower areas of a room, and also to be disposed in the line of vision of a person engaged in the performance of some work to protect the persons eyes from laterally projected light rays.

The invention has for its general object the provision of a lamp shade of the indicated 5 character embodying improved features whereby the shade may be quickly and easily applied to and removed from a lamp, and which will be of simple, efficient and inexpensive design.

The nature of the invention and its distinguishing features and advantages will appear when the following specification is read in connection with the accompanying draw ings, in which.

Figure 1 is a sectional view of a lamp shade I embodying the features of the invention shown applied to a lamp, the latter being shown in dot and dash lines;

Figure 2 is a perspective view of the shade; Figure 3 is a perspective view of the retaining means of the shade.

Referring now more particularly to the drawings, it will be apparent that there is shown a combination of a lamp shade 10 hav ing arranged therein retaining means 11 which is adapted to be brought into engagement with a globe 12'of a lamp to detachably retain the shade 10 in place on the globe 12.

The shade 10 is of annular construction, so as to be open at the top and'bottom to permit light rays from the lamp to pass upwardly and downwardly. The shade 10 may be made of any suitable material, and, in the present instance, is made of metal. The shade 10 consists of two parts, in thepresent in-' stance, each part having a spun edge to provide a bead or channel, the channel of the upper part fitting within the channel of the lower part to present an annular groove 13 in the inside of the shade'any suitable distance between the upper and lower edges of the shade preferably about midway between the edges. The upper and lower ends of the shade are flared in the present instance.

a The retaining means 11 may be of the practical construction shown, including a wire ring 14 which is split so as to expand and contract, and the'terminals thereof are disposed radially inward-to begrasped for the purpose of contracting the ring to enter it into the groove 13 and to remove it therefrom. A suitable number of pieces of spring wire are used. Each of these pieces is wrapped around the ring 14, as at 15, to present an upper group of spring fingers 16 and a lowergroup of spring fingers 17. Each of the fingers 16 and 17 is arcuate in the present instance so as to conform to the contour of the lamp globe 12. It is to be understood, however, that each of the fingers may be of any other shape or formation. The free end of each finger 16 and 17 is rebent, as at 18, so as to easily slip on and off of a globe. When the ring 14; is entered into the groove 13 in the shade 10 the retaining means 11 will be held in place therein and the shade will be ready for use.

From the foregoing it will be apparent that a lamp shade having the features set forth above may be readily brought into engagement with a lamp globe by exerting a certain amount of pressure on the shade whereupon the fingers 16 and 17 will severally engage the globe and thus detachab-ly retain the shade inplace. It will also be apparent that the shade 10 may be readily detached by exerting a pull on the shade. It will also be apparent that light rays will be permitted to pass upwardly and also downwardly from the lamp for the purpose of illuminating the upper and lower areas of a room, .and that the shade will prevent light rays from being projected laterally.

'Claims:

1. The combination of a lamp shade open at the upper and lower ends and havingan annular groove in the inside thereof, and lamp globe engaging means to retain the shade in place on the globe, said means consisting of a resilient split ring to be sprung loo 3 into said groove to connect said means With said shade within the same, and upwardly and downwardly projecting spring fingers on the ring to engage said globe.

2. The combination of a lamp shade open at the upper and lower ends and having an annular grove in the inside thereof, and lamp globe engaging means to retain the shade in place on the globe, said means consisting of a resilient split ring to be sprung into said groove to connect said means with said shade within the same, and members secured to the said ring to provide upper and lower groups of spring fingers to engage said globe.
